The problem of wastewater disposal affects not only third countries, but also world giants such as China or the United States of America.The European Union and the Commonwealth of Independent States are no exception.The increasing use of organophosphate pesticides requires the search for new, more efficient and cheaper ways to dispose of their resi
This research is motivated by deficiencies in the science learning process.It is known that the dominant teaching method used is lecture, which minimally involves students in active learning.As a result, students are not given extensive opportunities to independently find solutions to problems or understand the concepts presented.This research aims
We study the potential of infrared (IR) heaters in combination with IR reflective walls to reduce heating energy demand in buildings.Using IR heaters increases radiant temperature.Combined with IR reflective walls, less radiant heat is absorbed by the surrounding walls, and more is reflected to and absorbed by the occupants.This allows for lower ai
We present new distribution information for 19 species of Costa Rican ERPA SENS COLD SORES LIP BALM birds.Thirteen species show changes in altitudinal distribution, 9 are recorded at higher elevations such as Egretta rufescens (Gmelin, 1789), Heliomaster constantii (Delattre, 1843), Myiozetetes cayanensis (Linnaeus, 1766), and Lon
Abstract Background Cucumbers (Cucumis sativus) are known for their plasticity in sex expression.DNA methylation status determines gene activity but is susceptible to environmental condition changes.Thus, DNA methylation-based epigenetic regulation may at least partially account for the instability of cucumber sex expression.Do temperature and phot
